Carbon Steel Threaded Nipple, API 5L Grade B, PSL 1, 1/2 Inch

China carbon steel threaded pipe nipples are short, close-tolerance barrel sections used to extend or connect threaded piping runs. This model is produced from API 5L Grade B PSL 1 material in 1/2-inch (DN15) size with SCH 80 wall thickness for enhanced pressure capacity. Cut to 200 mm length and finished with NPT tapered threads on both ends, it ensures tight, vibration-resistant seals in oil, gas, and industrial utility systems without the need for welding equipment.
